What are some roots of corruption in Indonesia?

Herd mentality, we perceive corruption acts as okay because everybody else is doing it. Probably not the root, but only what makes corruption as wide spread as it is now

The strongest evidence for this is the case of Alif and Ibu Siami back in 2011. They were evicted from their hometown to be safe from angry neighbours protesting in the front of their house. The case was reported in mainstream media and received significant public attention.

In June 2011, Alif and his mother got into such difficult position because, in the national exam in his primary school, Alif was told by a teacher to give out his answers to all of his friend during the exam. Alif told his mother, Ibu Siami, who reported this mass cheating and the said teacher to the Education Board in town. Which led to the investigation at the teacher and anger from neighbours swelling at Alif and her.

The latter was easily the saddest thing in my opinion.

I cheated at schools' exam (not at the national exams but it's one and the same really) and, in retrospect, feel ashamed of ever doing it, knowing that I'll pass anyway. But I remembered seeing every other person was doing the same thing, some teachers told me it's bad, I shouldn't, but my peers told me otherwise!

Now imagine Alif listening to the teacher telling him to help his friends. Doing the exam. The teacher probably gave him no reasoning at all but told him it was okay and he should. You see, it was exactly what happened to me but, coming from somebody with authority. And then he also needed to flee the city because he made people angry for being such a tattletale of course.
